NEW YORK (CNNMoney) A young computer whiz from New York City has launched a site to http://www.cheapjerseys11.com/ help people buy cheap plane tickets. But an airline company and its travel partner want to shut him down.

The idea is that you buy an airline ticket that has a layover at your actual destination. Say you want to fly from New York to San Francisco you actually book a flight from New York to Lake Tahoe with a layover in San Francisco and get off there, without bothering to take the last leg of the flight.

This travel strategy only works if you book a one way flight with no checked bags (they would have landed in Lake Tahoe).

It not like these tickets are the cheapest all the time, but they often are.

In the lawsuit, United and Orbitz call Skiplagged competition and allege that it is promoting prohibited travel. They want to recoup $75,000 in lost revenue from Zaman.

Zaman said he knew a lawsuit was inevitable but he points out that there nothing illegal about his web site.

He also said he has made no profit via the website and that all he done is help travelers get the best prices by exposing an in airline prices that insiders have known about for decades.

city ticketing] have been around for a while, it just hasn been very accessible to consumers, Zaman told CNNMoney.

Indeed, city, ticketing is no secret among frequent fliers, said Michael Boyd, President of Boyd Group International, an aviation consulting firm in Evergreen, Co. Boyd worked as an American Airline ticket agent 30 years ago, and says he was trained at the airline to help customers find city fares.

don think it illegal what he doing, Boyd said. But lawsuits are expensive and it could end up costing the young entrepreneur who has irked the two billion dollar corporations.

Airlines usually offer cheaper fares for some destinations that are not regional hubs, Boyd said. Many of these flights are routed cheap jerseys through more popular destinations. But if a lot of people take advantage of that discrepancy it could hurt the airlines, which is why they want to shut him down.

Zaman said Skiplagged is just a project. and United declined to discuss the lawsuit. Orbitz said in a statement that it is obligated to uphold airline fare rules.

Other travel experts say that the airlines may not achieve much if Zaman site is shut down, especially in a world where information is becoming more readily available.
